Tests of intelligence and structured measures of emotional status, aptitudes, and achievement alone do not suffice in predicting the vocational adjustment of the mentally retarded. Since the main concern is the evaluation of the many aspects of behavior which make the individual a unique and changing person, a format was developed which included a particular battery of psychological tests which assessed intellectual capacity and functioning, personality characteristics, academic achievement, aptitudes, and preferences. Tests were selected for their usability and appropriateness with the mentally retarded. The importance of the format is that it included the author's interpretations and insights based on the examinee's responses and reactions to the testing program. The test findings were critiqued, and the clinical interpretations were presented. Some conclusions and recommendations were: the focus of the assessment should be on the identification of areas of strength rather than on weakness; social competence is one of the most important determinants for vocational functioning; it is more appropriate to make an assumption of positive adaptation on a meaningful criteria of employability and social integration until negative evidence appears, rather than to assume a poor prognosis until positive evidence appears; and finally that predictive measures should be more as estimates of preparation for the next step in training or placement than as determiners of the future.
